Ol'llllll N0. 2,333, W November 25, 1941, M10]! for m hematite-asthmaimreeling bundles ofcoiled' m and, particularly, to an improvedapparatusfor Heretofore, it has :been usualpractice to;

supp y wire or rod to a wire-drawing maehine pr;

. other wire-working machine by providing afdilii rality of bundles ofcoiled wire or rod for passage through the machine and feeding the wirered I of the bundles individually into and through the machine. Insuchpractioe, after each bundle of wire was consumed, the machinevhad tobe stopped until the next bundle of wire or rod was properly placed forunreeling and threaded into the machine and attached to the end of thewire of the previous bundle that has passed therethrough. This resultedin a lossoi' time and slowed up production considerably. Also, it wasnecessary for the operator to always be on duty in order to stop themachine before the bundle of wire passing therethrough had completelypassed thereinto. v

In the present invention, all of the abovedisadvantages have beeneliminated and there is provided an unreeling apparatus or device whichpermits continuous operation of the wire-working machine.

-wlth which it is to be used.

It isstill another object of the present invention to provide animproved apparatus or device for unreellng wire, rod and the like whichis strong and rugged in its construction and. consequently, one that iseasy and inexpenslveto maintain. I

Various other objects and advantages of this invention will be moreapparent in the course of the following specification and will beparticularly pointed out in the appended claims.

In the accompanying drawings there is shown, for the purpose ofillustration, one embodiment which my invention may assume in practice.

Figure 4 is an elevation of the outer end of one of the upper arms andthe parts associated therewithtand' Figure 5 in smaller plan shuntomgure 1 showing the bundlesof coiled wire in position thereon.

. Referring more. particularly to the drawings,

the improved apparatus or device for unreeling bundles of coiled wire,rod and the like, comprises a base or pedestal 2 which is adapted to beplaced on or secured to the ,floor opposite the wire-drawing or otherwire-working machine with which it is to be used, preferably by means oflag screws I or any other suitable means.

preferably a cast iron frame or body member 6.

having roller bearings 'l and 8 associated therewith for loosely androtatably supporting the body member 6 on the upper portion of the shaft5. There is also arranged in a cylindrical opening 9 arranged in thebase or pedestal 2 to one side of the shaft 5, a plunger pin ill, theupper end of which is adapted to cooperate with spaced member 8.

of which is adapted to hold a bundle of coiled wire or rod. It will beseen that only three pairs of arms'are shown, but it will be understoodthat any number of pairs of arms as desired may be provided. Each pairof these arms consists of an upper U-shaped arm l5" having its inner'endpivotally attached to theupper portion of the body member 6 by means ofa pin is and a cor-' respondingly-shaped lower arm ll spaced therebelowbeing pivotally attached to the lower portion of the body member 6 by.means of a pin The upper arm l5 and the lower arm I! of each of thepairs are interconnected by means of a link member I! with the upper endof the link being pivotally connected to the upper arm I I5 forwardly ofthe pin It by means of a pin 2| member IS, the purpose and the lower endof the link being pivotally connected to the arm I] rearwardly of thepin I! by meansof apin 2|. f

' There is arranged preferably betweenthe arms l5 .and i1-of each of thepairs, a pin 22 pivotally arranged on the side of the body member 6.

There is securely attached tothe pin" atone.

end thereof a lever 23 having a counterweight 2| arranged on the outerend thereof and an angular actuating portion 25 disposed on the innerendthereof which is adaptedto extend to of arms. There is also securelyattached to the pin 22 intermediate the link thereof a dog member orpawl 2i which is adapted to cooperate with a notch 21 arranged on theinterconnecting link scribed hereinafter. I There is associated witheach of the pairs of arms above the upper arm l5 thereof, anarcuatemoved downwardly so as to be positioned over the coil andwith theouter free end thereof resting on the outer end of the arm l5. One ofthe arms with the bundles thereon is'then aligned with the machine towhich the wire is adapted to pass and the front end of the wire isthreaded into the machine so as to pass therethrough."

' The end of the wire at the rear of this coil is then welded to the endof the wire at the front the side of the body member 6 between the pairsof which is to be deshaped coil retaining or flipper member 28 havingits inner end loosely pivoted to the upper porg tion of thefoody member6 at 29 with the outer free end of the upper arm li. Each of the armsI5-.prefera;blyhas arranged thereon, adjacent the outer end thereof andsecurely attached thereto as at 3|, an upwardly .angularly extendingU-shaped guard member 30 which is positioned adiacent the free end ofthe flippermember 28 and adapted to hold the coils of wire thereon. Eachof the lower arms IT of each of the pairs has. arranged therewith andsecurely attached thereto, as at, adjacent the outer end thereof, asimilar U-shaped guard member 33 which extends downwardly and outwardlyfrom the arm. l1 .with the bottom free end thereof adapted free endthereof adapted to rest on the outer of the coil on the next succeedingpair of arms and the end of the-wire at the rear of the coil is weldedto the end of the wire at the front of the coil on the next succeedingpair of arms. The device is now ready for operation and the wire isdrawn off the pair of arms opposite the machine and, when the coil ofwire thereon is depleted, the, device is rotated by the pull of the wireon the next pair of arms by the wire-working machine so as to positionthe coil on this pair of arms opposite the machine and the feeding ofthe wire is transferred to the coil thereon. As the device rotates, itwill be seen that the bottom of the coil of wire on that pair of armsadapted.

to be positioned in alignment with the wire working machine strikes thebumper member I! mounted on the floor, thereby preventing the furtherrotation of the device but permitting the pair of arms to pass thereoverafter the coil thereon is depleted so as to permit the next coil to-beproperly positioned opposite the machine.

The bundles of coiled wire are then successively to rest on preferably asteel or other suitable annular plate member 34 arranged on the floor 7around the bottom of the base 2 which is adapted to support the outerfree end of each of the lower arms I5 and also to prevent movement ofthe coils over the free ends of the arms. There is also positioned onthe floor and suitably attached thereto within the annular steel platemember 34 and opposite the position that the coils. of wire assume onthe pairs of arms, a,

bumpermember 35 of any suitable shape and which is adapted for a purposeto be described hereinafter. The U-shaped guard members 3| and 33 arepreferably formed from a rubber sheathed ruining machine cable.

The apparatus or device as above described operates as follows:

A bundle ofv coiled wire or rod is first placed on each of the pairs ofarms as shown inv Figure 5. To place-the calls on each of the pairs ofarms, the. flipper member 28 is first moved upwardly away from the upperarm I5 and out of contact therewith as shown in the broken linesof'Figure 2, and the respective lever 23 is then actuated by manuallyforcing the angular portion 25 thereof '1 extending between the pairs ofarms downwardly, thereby disengaging the dog' or pawl 26 from engagementwith the notch 21 of the respective link' l9, thereby permitting theouter free ends of the. arms I5 and II to move toward each other, asalso shown in the broken lines of Figure 2. While the arms i5 and I1 aretogether,

the coil of wire is,placed thereon and, the upper arm is then movedmanually upwardly until the dogor pawl 26' engages the notch '21 in thelink I! due tothe action of the counterweight 24 and the arms aresecurely held in their spaced apart position thereby. The flipper member28 is then placed, as described. on the pair ,0! arms on which the coilpreviously thereon has been depleted and the end of the wire at thefront thereof 'is welded to the end-of the wire at the rear ofthepreceding bundle of coiled wire that preceded before on the nextsucceeding pair ofarms. Thus, it will be seen that, with such anarrangement, the wire or rod is fed continuously to the wire-workingmachine. It will be understood that the flipper member 28 and the rubbersheathed guard 30 on the end of the upper arm l5 and the rubber sheathedguard 33 on the end of the lower cm H act to retain the convolutions ofthe coiled wire on the arms, thereby permitting but one coil orconvolution at a time to pass therefrom when tensionis applied to theend of the wire or rod by the wire-working machine as shown in Figure 4of the drawings.

It will be seen that the pin Ill, cooperates with the lugs I! on thebottom of the rotatable body member 8 to prevent the same fromrebounding upon rotation after the bundle to be positioned strikes thebumper member 35 thereby securely locking the body member 5 in positionafter the movement thereof so as to maintain the particular pair of armsfrom which the wire is'being drawnby the machine in alignment therewithuntil the bundle of wire thereon has been depleted therefrom.

As a result of my invention, it will be seen that after one bundle ofcoiled wire has been depleted, another coil of wire is automaticallypositioned in alignment with the machineand an uninterrupted supply ofwire is delivered thereto.

, While I have shown and described one embodiment of my invention, itwill be understood that this embodiment is merely for the purpose ofillustration and description and that various other forms may be devisedwithin the scope of.
